This PWM Controller circuit is ideal for controlling small motors with 2A maximum current consumption. For higher currents you need additional cooling for T2 and increase C2 value. This pwm motor ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

The FAN400A is a highly integrated PWM controller designed to provide a low-cost total solution for flyback converters. It’s green-mode function provides off-time modulation to linearly decrease the ...

For the PDF version of this article, click here. Over the years, power supply designers have been persuaded that current mode is superior to its voltage-mode counterpart. As a result, the major PWM ...

Linear Technology Corporation has introduced the LTC3805, a current mode, programmable frequency pulse width modulation (PWM) controller said to reduce the size and complexity of flyback power ...
